论文摘要
我们展示了一个有限的群体，其第二个共同体包含一个薄弱的阶级，但没有有限的阶级。作为一种应用，我们反驳了格罗莫夫的长期猜想，内容涉及封闭歧管的通用覆盖物上的差异形式的有界原语。
We exhibit a finitely presented group whose second cohomology contains a weakly bounded, but not bounded, class. As an application, we disprove a long-standing conjecture of Gromov about bounded primitives of differential forms on universal covers of closed manifolds.
